Combine node atttributes from two lists

Based on Create list of nodes by copying from another lists, I would like to combine the attributes of a node in both lists. Let's say I have the following xml:

<root>
    <vo>
        <field name="userLoginName"       nameLDAP="uid"              type="String"/>
        <field name="displayName"         nameLDAP="displayName"      type="String"/>
        <field name="firstName"           nameLDAP="givenName"        type="String"/>
        <field name="lastName"            nameLDAP="sn"               type="String"/>
        <field name="mail"                nameLDAP="mail"             type="String"/>
        <field name="userPassword"        nameLDAP="userPassword"     type="String" hidden="true"/>
        <field name="center"              nameLDAP="center"           type="String"/>
    </vo>
    <input>
        <field name="userPassword" mode="REPLACE"/>
        <field name="oldPasswordInQuotes" nameLDAP="unicodePwd"       type="byte[]" mode="ADD"/>
    </input>
</root>

and I would like to combine both lists as in the question refered before, but taking the attributes from both lists. So in this case the output would be soemthing like this.

<field name="userPassword" nameLDAP="userPassword" type="String" hidden="true" mode="REPLACE"/>
<field name="oldPasswordInQuotes" nameLDAP="unicodePwd" type="byte[]" mode="ADD"/>

The field userPassword combines the attributes from vo/field[@name = 'userPassword' plus the attributes from input/field[@name = 'userPassword'. If an attribute is present in both input/field and vo/field, the value in input/field whould take precedence. For the field oldPasswordInQuotes there is no corresponding node in vo, so it should be copied as it is.

This may actually be simpler than you think:

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" version="1.0" encoding="utf-8" indent="yes"/>

<xsl:key name="vo" match="vo/field" use="@name" />

<xsl:template match="/">
    <xsl:for-each select="root/input/field">
        <xsl:copy>
            <xsl:copy-of select="key('vo', @name)/@*"/>
            <xsl:copy-of select="@*"/>
        </xsl:copy>
     </xsl:for-each>
</xsl:template>

</xsl:stylesheet>
